Seoul Viosys begins production of rare-earth-free white light emitter

Seoul Viosys has begun manufacturing a white light emitter that does not rely on rare‑earth elements. The company’s new production line signals its entry into the market for this type of lighting component.

The move is notable because many conventional white‑light technologies depend on rare‑earth materials, which can create supply‑chain constraints and environmental concerns. By offering a rare‑earth‑free alternative, the firm may help lessen those dependencies and support broader sustainability objectives in lighting and semiconductor applications.
